I will be switching to a return type rail on my 04 lq4 witch is caurrently non-return. So, what do you do to pulse dampner? I'm planning on being able to run 18/20 lbs of boost, am planning on two bosch 044 's and an aeromotive boost referenced regulator thanks

nothing, run a new feed line -10 and use stock feed as return

So does that mean no need for the aeromotive reg? And just leave it connected the way is ? Seems way too easy....... (surely It's nessacary to spend more money lol!)

Feed and return at the regulator, then run a line from regulator to OEM rail. Leave the pulse damper.

Hey forcefed, so your saying just use the non return rails and hook up the way you suggest, i do like that way, seems the simplest. I thought "best" or most "consistent "way to regulate fuel pressure was to use a return rail, feed it first from the pump, then the return off the rail to the regulator. Is it really 2 different ways of doing the same thing, or is it high horsepower and/or boost levels That would make the difference? Thanks

The way pictured has worked to 900ish whp on E85. Very capable setup for most builds. More than enough for pump/race gas builds to 1000+ IMO.

As forcefed said, it works well.

On both of these setups I used the stock rail and returned off the regulator.




With dual walbro 430s and the second pump on a hoobs switch there's no spike in fuel pressure.

Yea planning the second pump on a hobbs also. I have the option of either way, just want it to be as "foolproof "as possible and not have to chase my tail because I should have done something different . Since it seems that I'll keep the non return line rail, I do have the option of using rails and intake off a 08 truck motor, the intake that looks like tbss one with the square stainless rails.what do you guys think about that one? Any benefit for a boosted motor?

I have 2 044's pushing through a -8 to the factory truck rails with a -6 return. Factory reg works good.
